I don't think the SK hit comes with a stiffer line pressure spring. So you will need to adjust the spring you have to it's maximum pressure. You can just use a stack of washers to make the L/R servo solid.
I guess Im not even sure what controls line pressure. I've heard/read about the solid spacer deal. Although not sure what benefit it would have. I know when people bump the LP too much, they start cracking/calking piston. I'll have to look into it all again, its been a while. I plan to upgrade the pistons in the 46, so I'll play with things a lil more then.
